1Discover how your web browser is already caching tons of stuff to make websites lightning fast, and why this matters for system design.
Ever noticed how Facebook loads instantly the second time you visit, but takes a moment on the first visit? Your browser is working like a super-smart librarian!
Client-Side in Action:
When you visit a website, your browser automatically saves:
Real Example: Netflix remembers where you stopped watching a movie on that specific browser. Switch to your phone? You might start from the beginning because each device caches separately.
The Magic: Instead of downloading the same company logo 50 times while browsing, your browser says: "I already have this!" and shows the cached version instantly.
Key Insight: "Client-side caching is like having a personal copy of frequently used items - no need to ask for them again!"
This is why clearing your browser cache makes websites load slower initially - you're deleting your browser's helpful memory!
